Hi,

I am trying to use enum's, but both HIDP_REPORT_TYPE and USAGE cause runtime error (compiles OK) "Unsupported argument type". HIDP_REPORT_TYPE is defined in HIDLibrary.java and USAGE is in USAGE.JAVA . HIDLibrary.java and USAGE.JAVA are attached.

Unsupported argument type hid.HIDLibrary$HIDP_REPORT_TYPE at parameter 0 of function HidP_GetUsageValue

result = hidLibrary.HidP_GetUsageValue( HIDLibrary.HIDP_REPORT_TYPE.HidP_Input, USAGE.UPG_MSR, linkCollection, USAGE.UID_TRACK_1_DECODE_STATUS, tk1DcdSts, preparsedData, readBuffer, capabilities.InputReportByteLength);
